Research And Design Of Computer Room Monitoring System Based On Internet Of Things Technology

The computer room is a large information storage center and management center.It serves a wide range of banking systems,public office systems and large building systems.In colleges and universities,the computer room must also undertake tasks such as teaching and examination.There are currently no targeted computer room monitoring products for this field.This paper designs a monitoring system for the university's computer room in the Xinjiang region.Based on the Internet of Things technology,the monitoring system uses ZigBee wireless sensors to obtain environmental parameters such as temperature and humidity,smoke,and sand in the equipment room.It obtains the operating status of various electrical equipment through RS-485 and Ethernet interfaces,and then completes the monitoring of the operating state of the entire equipment room.Based on the introduction of the research status of computer room monitoring at home and abroad,this paper analyzes the key technologies of the computer room monitoring system based on the Internet of Things technology.It studies the overall structure of the computer room monitoring system and the overall structure of the Internet of Things technology.It analyzes in detail the application of sensor technology,cloud computing technology,wireless sensor network and data mining technology in the Internet of Things.Secondly,it analyzes the overall design of the computer room monitoring system based on the Internet of Things technology.Through the analysis of the actual needs of the university computer room monitoring system,it determines the overall function of the computer room monitoring system.The overall functions include data collection and control management,data storage,user interface management,alarm management and auxiliary management.It compares with the analysis of the environment monitoring implementation of the equipment room to determine the circuit design based on the microprocessor and onboard switch,which can achieve all the functional requirements at a lower cost.The paper focuses on the detailed design of the data acquisition and control management unit of the computer room monitoring system.On the basis of the overall design of the monitoring and management board,the scheme of using 88e6321 switch and STM32 microcontroller is determined to realize data acquisition and communication transmission.It analyzes the circuit design of the small switch unit and the design of the microcontroller unit in detail,and gives the schematic diagram of the ZigBee communication unit,Ethernet communication unit and serial communication unit.It finally analyzed the software design ofthe computer room monitoring system.According to the function of the hardware platform,it is divided into five units: alarm unit subroutine,data storage unit subroutine,serial communication subroutine,ZigBee communication subroutine and Ethernet communication subroutine.It analyzes the main program and RS-485 communication subroutine design in detail,and finally discusses the overall design scheme of the monitoring platform.
